I'd add that such high abstraction as category theory (IOW "abstract 
nonsense"), isn't exactly a thing you apply specifically to RDF. RDF 
after all is just one data model in a long line of formal data and 
knowledge representation.

Thus, if you want to do a proper literature search for how it has been 
used in the past to solve similar problems, at the very least see how it 
has been applied to the relational model and its offspring in the past. 
If my memory serves at all right, the theory of schema transformations 
and/or mappings have already received some categorical treatment, as has 
database normalization, as have various particular data description 
logic derived particular data representations, and in particular the 
semantic data models of '80-'90 lore (one of them being Codd's RM/T).

The translation of all of that stuff onto the RDF graph model is then 
obviously just one morphism amongst others.
